OGDEN H. TAPPAN, OF POTSDAM, NEW YORK.

HAND-STAMP.

SPECIFICATION formingpart of Letters Patent No. 247,710, dated September27, 1881.

Application filed February 25, 1881. (N0 model.)

To all whom it may concern:

Be itknown that l, OGDEN H. TAPPAN, of Potsdam, in the county of St.Lawrence and State of New York, have invented a new and ImprovedHand-Stamp, ofwhich the following is a specification.

The object of my invention is a cheap and effectivestamp-canceling andpostmarkin g device for use in post-offices, and one which can be usedrapidly and on all kinds ofmail-matter.

The invention consists of two rollers, one for stamping or printing andthe other for canceling, journaled in a frame, the surfaces of whichrollers are supplied with ink from a superimposed ink-reservoir, therollers being adapted to be rolled or passed over and upon the lettersand stamps to mark and cancel the same.

In the accompanying drawings, Figural represents a vertical sectionalview of my invention; and Figs. 2, 3, and 4 represent like views ofmodifications thereof.

Similar letters of reference indicate corre sponding parts.

The frame A is of tin or other suitable sheet metal, and formed with anenlarged portion, which is of such size and shape as to permit themarking and canceling wheels B- B to be journaled in it in such mannerthat a portion of both wheels will besufficiently exposed below theframe for applying the ink for marking and canceling. The handle 0 ofthe frame is hollow and closed at the top with the screwcap 6, thusforming the reservoir for the ink d, which is retained in thereservoirand gradually supplied to the rollers by the sponge or otherabsorbent material E, held in the triangular chamber formed by thediagonal plates 6 e, secured to thetop of the frame, as shown. Theplates 6 e have the slots 6 6 formed in them, through which a portion ofboth wheels pass, and thus move in contact with the absorbent material Eto be supplied with ink.

The marking and canceling wheels, of suitable diameter and length, areformed of metal, rubber, celluloid, or other suitable material, and-maybe solid or formed with a core of different material. The marking orprinting cylinder or wheel B has raised letters formed on terial E forsupplying the ink to the surfaces of the wheels, a third wheel, I),bearing upon the rollers B B and revolving directly in contact with theink, as shown in Fig. 2, might be used, and the reservoir containing theink may be divided by the diaphragm f, containing the valve f, operatedby the rod 9, which passes through the screw-cap c, as shown in Fig. 3,by which means the ink contained in the space above the diaphragm may beadmitted to the absorbent material as the ink in the same becomesexhausted; or, instead of the diaphragm, the piston J, having the rod 1and forced down by the spring k, as shown in Fig. 4, might be used,which will keep the sponge or other absorbent material saturated, and bythis means ink of as heavy body as printers ink may be used.

Though I have shown and described my invention as applied forpostmarking and stampcanceling, it is obvious that it may also be usedfor dating and receipting, and for many other purposes, in which caseonly the printing-roller would be required.

A package of letters'is held in one hand like I OGDEN HEWITT TAPPAN.
